HAY-LOADER.

Specification of Letters Patent.

Application led July 24, 1916. vSerial No. 111,076.

.and useful Improvements in Hay-Loaders;

and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates broadly to improvements in harvesting machinery and more particularly to hay loaders,'the object being to provide a comparatively simple andvinexpensive yet highly eliicient loader having a uniquely constructed vertically adjustable guard frame above .its elevating apron for the purpose of effectively retaining the hay on the latter whether the crop be. light or heavy.

With the foregoing general object in view, the invention resides in certain novel. features of construction and inl unique combinations of parts to be hereinafter fully described and claimed, the descriptive matter being supplemented bythe 'accompanying drawings which constitute.- a part 4of ythis application and in which: v

Figure 1 isa side elevation of the improved loader applied; 'l f Y Fig. 2 is atop plan view thereof;

Fig. 3 is a central longitudinal section; and j A Fig. 4 is a detail transverse section showing the manner in which the jconveyer slats are fastened to the outermost belts.

In specically describing-the construction shown in the drawings above briefly described, similar characters will be employed to designate corresponding partsthroughout the several viewsand reference will be herein made to the numerous elements by slatted frame whose side bars are secured to the upper ends of the V-frames 3 and braced to the tongue 5 as shown at 7.

A pair of suitably shaped brackets 8 are secured to and depend from the lower or rear ends of the side bars of the frame 6, said brackets carrying appropriate bearings in which the horizontal-.transverse shaft i 9 lof a cylindrical drum' 10 isfrotatably mounted, said drumbeingdrivenlb'y means of a sprocket chain 11 and sprockets V12 and 13 from the axle 1, said sprockets '12 and 13 being keyed respectively 'on thesliaft 9 and the axle 1. l.

An auxiliary slatted frame 14 is pivoted at 15 to the upper vend of the'frame 6, a

roller 16 being mounted onthe pivotal axisas shown clearly .inFigs 1 and 3, while an f additional roller 17 fis disposed at the free endfof the frame 14, and flanged rollers 18 are secured by'brackets `19 and are positioned beneath the roller `16. "A pluralityl of endless belts 2O of canvas or the like are passedaround the drum 10 and over the rollers'16,v17 and 18, said belts having secured thereto a number of transverse conveyer slats 21which are preferably equipped with prongs v22. vTheV ends of the slats 21 -v terminate 'short of the rollers 18 as indicated in Fig. 4 in order that they may pass betweensaid rollers,and said ends are se'-V cured in U-shaped clips or the like 23 which e are provided with flat extensions 24 projecting beyond lthe Vends of the slats, said extensions being secured to the'outermost belts 20. This construction permits the endless belt conveyer to readily travel over the rollersv 18.,y

A guard frame 25 is disposed above and parallel with lthe frame 6,-the .side bars 26 kof said frame 25 being pivoted to the upper ends of parallel links 27V whose lower ends are pivotally connected to the side bars of said Yframe 6. By this mounting the frame 25 may be moved forwardly and in so doing will travel downwardly toward tlle frame 6 as shown in dotted lines in Fig. 1, or by moving-said frame 25 rearwardly, it will raise inrespect to said frame 6. For vmoving the frame 25 in this manner, a. hand lever 28 is fulcrumed atits lower end to one side of the frame 6 and at 29 has a'sliding connection with one of the side bars 26, a pawlA and rack arrangement 30 being provided for locking the frame 25 in anyof its adjusted positions.- 'Az plurality of rake teeth 31 are secured on a rock shaft 32 mounted on the lower end of the frame 25, said teeth being preferably tied together -near their lower ends by atie bar 33. A

crank arm 34 rises rigidly from the rock shaft 32 and is'connectedto a link 35 by a hand lever 36 which is carried'by thelower end of the frame 25, a suitable pawl andi-ack mechanism 37 being provided to lock said lever 36 in its adjusted positions. 1t will thus be evident that as the frame is adjusted vertically, the teeth 31 may be properly disposed and may be placed under suitable tension. j

The rack 38 of the mechanism 37 is secured at its ends to a pair of transverse bars 39 which extend between and are secured to the rear ends of the side bars 26, while at the upper ends of ksaid bars a rod 40 is disposed with its ends passing through apertures in said bars. A plurality of slats 41 of metal or wood extend longitudinally between the bars 39 and the rod 40 and co'- Voperate with these parts and the side barsV 26 in forming the guard frame 25 which is adapted to retain the hay upon the upwardly moving reach of the endless belt conveyer.

An auxiliary slatted guard frame 42 is disposed above the frame 14 and connected therewith by links 43 similar to those shown at 27, the rear end of said auxiliary frame having a rod Y44spaced in advance of the rod 40, the two being loosely connected by a plurality of short slats 45. while the side bars of the frames 25-and 42 are Vsimilarly joined by means of a pair of links 46, the ends of'these links being mounted pivotally on the rods 40 and 44. By this arrangement of parts, it will be obvious that forward or rearward adjustment of the V`frame 25 by means of the lever 28 will similarly adjust the frame 42. Furthermore, the angular relation existing between Ythe frame 14 and the frame 6 and between the frames 42 and 26 may bevaried as will be evident by a comparison of Figs. 1 and 3. ln the'latter figure the frames 14 and 42 have been `elevated for loading at a greater height and regardless of the position of said frames, they will be supported by bars 47 pivoted at its rear end to the rod 40, said bar having ratchet teeth 48 at their front ends which engage a rod 49 extending between the rigid arms 50 which rise from the front end of the frame 14. rEhe ratchet teeth 48 will successively engage the rod 49 as the frames 14 and 42 are forced upwardly and will thus automatically support said frames, but when the latter are to be lowered, it is first necessary to raise the bar 47 to dispose its teeth 48 to inoperative position. Y Y

As shown clearly in Figs. 2 and 8, the slats 42a of the auxiliary guard frame 42 are secured at their rear ends on the rod44 and at their front ends to a rod 42b which extends across the front end of said frame.

ln use, the tongue 5 will be connected to the rear axle A of a wagon W' so as to dis-j Vrespective functions in an etlicient manner.

From the foregoing taken in connection with the accompanying drawings, the construction, manner of operation and advantages of the improved machine will be read- Vily understood without requiring a more extended explanation, but in yconclusion l will .state that although certain specific features have been shown and described for illustrative purposes, numerous changes may be made in the scope of the invention as claimed without sacrificing the main advantages thereof.
